OCD induced by drug abuse

Hi everybody i've been strugling with something strange its like hocd but hocd could be only one part of it.
I don't get intrusive thoughts anymore, but the problem that caused me to start doubting in the first place is still here.
The very idea that i could be gay didn't come from thoughts about men but rather as an explanation to my emotional state following one night of ecstasy, basically after one hit of some crazy ecstasy (even the dealer called us crazy for taking a whole hit) i got depressed, my thoughts went all over the place, i wasn't sure whats real and what isn't, i thought i was losing my mind,i couldn't explain to myself why i was that way or why i felt so bad. so that combined with jokes that prior to this never bothered me i started feeling like something is wrong with me, i started feeling that i was somehow sexually inadequate, i had weird dreams, like my jaw was broken and while i tried to talk to anybody they would look at me like something was wrong but they were to polite to tell otherwise, i dreamt that i was having sex with a pig while people were looking at me and laughing, i was really losing it, i thought i became schizophrenic.(i've read about posible psychosis few days ago following one ingestion of MDMA and i actually found that common symptoms include schizophrenic like sympthoms)
I became really sensitive to every joke aimed at me, to make things worse i was smoking pot during all of this, even if it made me feel worse i wasn't quitting, and hocd came during one these nights when i was high. when one of my friends said that me and one other guy that was there looked like a couple, and i freaked out.
I connected the dots in a very stupid way:"What if i was feeling this badly because i am secretly gay and i unaware of it and i will feel this way until i give up on women and come out"
Next few days involved many other things that you can find all over this site so i wont bother you explaining how i was checking if i was attracted, how i avoided other men as much as i could etc.
The thing is this hocd came like a blessing, it focused me even if it was terrible at first it focused me, it gave me something that i could rationally look at, even if the first two weeks were terrible, as time goes by i feel better and better basically i realized that i didn't care whatever i was gay or not i just
the problem is i still have ticks from that night, i become light headed, i start sweating, start feeling that way, i feel for few moments like im losing it again and thats when the really weird thoughts start happening i get in that mode where i try to explain why im feeling that way and go trough that sexual inadequacy thoughts: Zoophilia, Homosexuality, Incest, Transexuality.
Or i have thoughts like that im dying,everybody is staring at me realzing what im going trough but they are just too polite to say anything, they all think im crazy/gay/inadequate/idiot.
Im calling hocd a blessing because while i was focused exculusively on that it helped me see paterns about this, i wasn't just jumping from one idea to another but i stuck longer on one and it helped me see this.
Using ERP reduced anxiety a lot, i can control this(Stop myself from doing compulsions), hell i can even live with this, compared too those first few days after that night this is paradise, now i can call it irritating rather than anxiety provoking.
What other tehniques could i use to make this better can anyone recommend anything? ERP works for sure i dont quite understand how CBT works.
Im writting this here because im not seeing a specialist because it is currently unavailable for free(unless you need to be hospitalized) and i lack funds for private one.
